Y. form of the invern-i 55 tion, are provided with an extension 58, projectwing 50, which extension carries an 58 for securing the corner element to its A locking tongue 6l is provided upon the end oi the wing 52 and this locking tongue is adapted for interlocking engagement with a slot 62, in' the immediately adjacent trapezoidal panel when the device is set-up in display position.

In this modied form o! the invention, the corner elements are secured to their respective panels by passing the extension 56 of each corner element through a slot 66, in the outer section of lts respective trapezoidal panel with the adhesive side thereof uppermost in such position that it may be adhesively secured to the inner iace of the trapezoidal panel as illustrated at 10, in Figure '1. l

The corner elements are preferably oi ornamental form and provide an ornamental nish to the device when it is in its set-up form. In addition to serving as ornamental, as well as securing means to retain the beveled border or frame in set-up position, the corner elements serve to hide the joint between the outer sections of the trapezoidal panels when the device is set-up for display and alsoserve as bracing elements for the corners of the beveled frame.

From the foregoing, it is apparent that the present invention provides a display device of the aforementioned character which is possessed of highly ornamental characteristics, is simple and cheap of construction and which may be easily set-up and knocked down as occasion may require.

Having thus described the invention, what is claimed as new, is:

l. A cardboard knockdown display device comprising a front panel, a trapezoidal panel hinged to each of the side edges of said front panel and adapted conjointly to define a beveled border for said front panel, a slot formed in each end of each of said trapezoidal panels, a. corner element, a tongue projecting from said corner element for reception in one of the slots of a trapezoidal panel to provide means for xedly securing said corner element to one of said trapezoidal panels, and a projecting from said corner element for reception in a slot in an adjacent trapeto position the trapezoidal panels in setup border forming position.

2.
